I'm loathe to try to update Qt to 5.8 on this machine since it's the one I practice capitalism on. I'll dump versions on the working personal laptop when I get home

Thanks for the detailed report! 👍

Can you confirm you get the same crash with other QtWebEngine projects, like scripts/testbrowser_cpp/webengine/ in the repo (run qmake && make) or QupZilla?

From the stack this looks a lot like a Qt bug I fixed in https://codereview.qt-project.org/#/c/171970/ - but that fix should have made it into Qt 5.7.1!

Maybe you can try to install python-tox (not sure how it's called on Fedora though), do tox -e mkvenv-pypi and try with ./.venv/bin/qutebrowser? That'll allow you to test with Qt 5.8 easily with it only being installed in a virtualenv, i.e. only affecting that subfolder.

The-Compiler · 2017-03-21T05:16:18Z

Some more ideas:

Can you double-check via your package manager that qt5-qtdeclarative is actually at 5.7.1?
Does export LIBGL_ALWAYS_SOFTWARE=1 change anything?
Can you show a bt full in gdb of the top 5 frames or so?

Neither crash

I was wondering if Fedora would ship a patch to do weird things here, but they just have a bunch of ARM/NEON patches... http://pkgs.fedoraproject.org/cgit/rpms/qt5-qtwebengine.git/tree/

Maybe you can try to install python-tox (not sure how it's called on Fedora though), do tox -e mkvenv-pypi and try with ./.venv/bin/qutebrowser? That'll allow you to test with Qt 5.8 easily with it only being installed in a virtualenv, i.e. only affecting that subfolder.

I started going down this rabbit hole but fell asleep before i could make it blend

Does export LIBGL_ALWAYS_SOFTWARE=1 change anything?

It does not crash when i do this.

Can you show a bt full in gdb of the top 5 frames or so?

I'll have to do this after work, we started using session cookies for SAML and it's harshing my cool.

The-Compiler · 2017-03-27T07:24:43Z

Any update on this, @rrix?

The-Compiler · 2017-04-04T17:19:39Z

Closing because of inactivity - I'll be happy to reopen if you have more infos though!

rrix · 2017-04-10T22:54:09Z

I've just been using it with the LIBGL_ALWAYS_SOFTWARE variable shoved in to it, and since I dont care about webgl and all that stuff, it's fine. It still crashes if I don't provide that, though.
